To (tZZ whom it may concern: to such adjustment by means of a set-screw,

Be it known that I, GEORGE E. CARD, of 2.

The thus-protected being inserted in a bayonet-groove,38, in the rear extremity, 21, of. the said sleeve having handle 25. Theforward edge of this tube has been adjusted longitudinally within socket5, a number of notches, 39, of unequal depths,

ac for apurpose presently explained, may be fixed and one or other ofthese notches receives a pin, rco

40, that projects from thecrayon holder. The

pin 40being once entered in one of these,

notches is prevented from escaping therefrom by the retractile force ofthe spring 35. The retraction or retrograde stroke of the crayon, andconsequently its forward or efiective stroke, is manifestly limited bythe depth of the particular notch in which the pin 40'happens to beengaged. When withdrawn from the notches 39, the stem 29, with itsattached crayon-holder,can be rotated on its axis, so as to be easilypresented to any one of the notches 39.

While primarilydesigned and heredescribed as a retouching-instrument,the device is also applicable to the kindred uses of stippling and likeartistic work.

The form here selected to illustrate my invention is manifestlysusceptible of various modifications. For example, the flexibletransmitter niay be attached directly to the motorshaft.

In testimony of which invention I hereunto set my hand.
